Ergothioneine is a naturally occurring amino acid and is a thiourea derivative of histidine, containing a sulfur atom on the imidazole ring. This compound occurs in relatively few organisms, notably actinomycetota, cyanobacteria, and certain fungi. Ergothioneine was discovered in 1909 and named after the ergot fungus from which it was first purified, with its structure being determined in 1911. Ergothioneine is a natural antioxidant that can protect cells in the human body and is an important active substance in the body. Ergothioneine, as a natural antioxidant, has entered people's vision. It has various physiological functions such as clearing free radicals, detoxifying, maintaining DNA biosynthesis, normal cell growth, and cellular immunity.
